The subdirectories contain

core_src: problem-independent source code prob:* : problem-specific source code.

Typical workflow:

make and run

cd prob:kerr_torus

make newrun

run, leaving some diagnostic info in harm.out

./harm >& harm.out

... this takes about 45 min on a mid-2015 macbook pro.

for a longer run, edit decs.h and change N1 -> 256, N2 -> 256

analyze

look at log(density) in x1-x2 coordinates - requires imagemagick

display images/im_logrho_0400.ppm

make a useful imaging program

make rz_image

then make a set of movies - requires ffmpeg

sh ./make_movie.sh

have a look:

vlc images/logrho_rz.mov

then look at contour plot of log(density) in dump040

./dump.py 40

repeat, wiping out data from last run.

make newrun

another test case

cd ../prob:explosion

make

./harm >&! harm.out

... this takes about 7 min.

etc...
